Designer: Pantazis Houlis
Goal: There are two solved configurations, (1) the external cube is black, and the internal cube is yellow, and (2) the external cube is yellow and the internal is black. The goal of the puzzle is to go from one solved configuration to the other.

Notes: This puzzle is based on the well known 4D structure hypercube, and moves between the 3D projections of the hypercube.

Cube Art

Designer: Durandus Dijken
Goal: Position the magnetic blocks on the magnetic plate and make a cube and get the same four colors on each of the six sides of the cube. There are three solutions (as hinted in the plate diagrams).

Notes: Though the solution algorithms remain the same as a normal 2x2x2, the challenge lies in determining the solved state. Each type of groove can hold multiple shapes of bumps: the rectangular grooves can hold square bumps, rectangular bumps, triangular-prismatic bumps, and cylindrical bumps, as they all have the same cross-section in at least one direction. Some bumps are also placed ambiguously, so certain pieces could go in multiple places. However, there is only one solution that has all the grooves filled perfectly by bumps.

Notes: This puzzle turns on six different axes. The three axes going through the four-sided vertexes can be turned in increments of 90 degrees, and the three axes going through the diamond-shaped faces can be turned 180 degrees.

Designer: Simon Nightingale
Goal: Lock the box, and then unlock it. The starting/unlocked state is with the boxes separate and no loose internal parts. The goal/locked state is with the small box inside the larger box (enclosing the internal space) and again with no loose internal parts.

Notes: This puzzle was designed with three goals in mind: all pieces of the same thickness, unique solution, and difficult or impossible to solve using puzzle-solving computer software. The puzzle incorporates the “missing area” principle into a 3-D box-packing puzzle.

Purchase: Two sizes of the puzzle will be available until supplies are exhausted: (a) standard size with pieces and box made of walnut, and (b) double-scale (2x) size with pieces and box made of exotic woods. The 2x size have (1) Bocote pieces and a Bloodwood box.

Designer: Yuta Akira
Goal: Starting from the position shown, free the ring from the cage.

Materials: Stainless steel, wood
Classification: Disentanglement

Sliding Put Together Puzzle

Designer: Ton Delsing
Goal: Put the 15 pieces in the tray to construct the digits 1 through 9 in numerical order. Then slide the pieces to form a magic square (you must first determine how this magic square can be constructed).

Notes: Techniques for solving Spiral-2 (or Snail-2) are used to solve Spiral-4.

Purchase: Contact the designer by . Only limited number of hand-maded puzzles are available.

Spots

Designer: Steve Kemp
Goal: Place 8 magnetic tiles on each face of the base cube so that there are 1 through 6 spots shown on the six faces. However, unlike a standard die, the spots are positioned asymmetrically.

Designer: Pantazis Houlis, Arcady Dyskin, Alexei Kanel-Belov, Elena Pasternak, Yuri Estrin
Goal: Place the four tetrahedrons inside the frame so that no piece is loose. There are at least two different solutions.

Notes: This puzzle turns on 10 different axes. The eight axes around the equator turn 180 degrees, while the two axes at the four-sided vertexes can turn in 45 degree increments, allowing for shape-shifting.
